I bought Garmin's Topo DVD for my Rino. Its must be similar to what Mr. Gizmow is writing about. Even though you may not need the contour intervals, most topo maps will include geographical place names such as streams, lakes, springs, and mountain peaks. Most roads show up but some are only labeled as "road" or "unpaved road". I also us Garmin's Base Camp as I can either plan a route and send it to my GPS, or save a track on my GPS and send it to Base Camp on my computer. Having the contour intervals allows me to get a better lay of the land. FYI, mapping software purchased on a microSD card can only be used on one GPS unit, as the DVD can be shared. My Dad, our hunting partner, and myself split the cost of the DVD.
